Technological research is performed on the comprehensive utilization of reclaimed wastewater from softener,wastewater and waste gas from boiler production.Three kinds of wastes are mixed in a certain proportion to carry out chemical reaction.The regenerated water can be utilized effectively,reducing environmental pollution.After comprehensive treatment,the quality of regenerated water can meet the requirements of system reuse and oilfield reinjection,which reduces wastewater emission and treatment cost,saves energy,and is conducive to the green production in oilfield.
